GASOLENE-BURNER.

SIECIFIGATION forming part of Letters Patent No. 665,670, dated January8,1901.

Application filed January 4:, 1900. S ri l No. 3'79. N m l To all whomit may concern! Be it known that I, HENRY BOUNDS CARY, a citizen of theUnited States, residing at Los Angeles, in the county of Los Angeles andState of California, have invented a new and useful Improvement inGasolene-Burners, of which the following is a specification.

My invention relates more particularly to an appliance for generatingthe vapors in starting the burner into operation. Said generatorisapplicable to various forms of burner, but is especially adapted for usewith a form of burner known as an open Bunsenburner and for which I havefiled an application for Letters Patent of the Uni ted States, SerialNo. 715,237, filed May 1, 1899, and in which a generating-chamber isprovided at the end of the burner opposite the jet-piece and a pipeleads from the generating-chamber to supply the jet-piece.

An object of my invention is to provide convenient andthoroughly-effective means for quickly and readily generating the vaporfor starting the burner into operation.

Another object of my invention is to provide for readily igniting thevapors in the generator from the flame from the burner, and vice versa.I

The accompanying drawings illustrate my invention.

Figure I is a perspective view of my improved gasolene-burner. Fig. IIis a side elevation in longitudinal section on line II II, Fig. III.Fig. III is a front elevation of the burner. Fig. IV is a cross-sectionon line IV IV, Fig. II. Fig. V is a fragmental plan view to illustratethe front end of the generating-shell.

(1. indicates the generating-chamber.

b indicates the body of the burner proper for which this invention ismore especially designed to be used.

0 indicates the pipe leading from the generating-chamber for supplyinggasolene or vapor to the main burner jet-piece d.

e indicates an auxiliary jet-piece connected with the jet-pipe c andarranged to direct a jet along beneath said pipe.

f indicates a shell arranged beneath the pipe to inclose the jet andprovided with air-inlets g g and extending toward the generatingchamberand provided near such chamber with an outlet h for the flame and withan imperforate mixer-section h between the airinlets and the outlet h.Preferably the shell is in the form of a trough, and the openings areabove the bottom of the trough, and the trough extends underneath thegenerating chamber.

'6 indicates the gasolene-supply pipe, which opens into thegenerating-chamber. j indicates the Valve for controlling the same.

In practical use to start the burner into operation gasolene will beturned on through the supply-pipe 'i and will flow into thegenerating-chamber a and thence into the jetpipe 0 and to the auxiliaryjet-piece e, which will then be opened to allow the gasolene to flow outbeneath thejet-pipe Q. will be caughtin the troughfand Willthere beignited by the operator. The flame rising from the trough will heat thej et-pipe and the gasolene therein and will thereby produce theinflammable vapor,which then flows through the auxiliary jet-piecee andthrough the duct inside the shell or trough f beneath the j et-pipe 0.At first while the pressure is low and the hydrocarbon vapor ispractically undiluted with air it will issue at and can be ignited atthe air-inlets g g and will burn all along the jet-pipe above theopenings of the shell, thus to quickly heat the jet-pipe; but as thetension of the vapor increases the velocity of the jet will carry itthrough the shell and air will be intrained at the openings 9 g and willbe carried into the imperforate mixer section h of the shell, where itwill become mixed with the hydrocarbon vapor. The mixture of air andhydrocarbon vapor formed in the mixer-section h of the shell will be ofa proper richness of hydrocarbon to ignite as it issues at h and willthere produce a flame to heat the generating-chamber a, as Well as theend of the jet-pipe c. When the vapor has been brought to a sufficientlyhigh tension, the main jet-piece at will be opened and the vapor-jetwill be blown through the body of the burner, and when it issues at thefarther end of the burner it will be ignited by the flame from theauxiliary jet, and the burner will then come into perfect operation. Theauxiliary jet may then be cut off; but so long This gasolenecan as themain jet is ignited the auxiliary jet may be ignited at any time bysimply opening the auxiliary jet-valve k. The trough formed by theshellfbeing open at the front end, as indicated, and extending beneaththe generating-chamber conducts the inflammable vapors to the front ofthe generatingchamber, thus to beignited by the flame from the burner.The generator-jet Will thus be ignited Whenever it is turned on Whilethe burner is in operation. In case the tension of the vapor shouldbecome too low at any time the auxiliary jet will be turned on and itsflame used to produce a required heat for the generator.

m indicates a clamp by which the shell f is detachably attached to thejet-pipe c.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In a gasolene-burner, the combination of a generating-chamber; a mainjet-piece; a pipe communicating between the generating-chamber and themain jet-piece; an auxiliary jet-piece connected with said pipe andarranged to direct an auxiliary jet along beneath said pipe; and a shellarranged beneath the pipe to inclose the auxiliary jet and provided withair-inlets and extending toward the generating-chamber and provided nearsuch chamber with an outlet for the flame and with an imperforatemixer-section between the outlet and the air-inlets.

inlet and the flame-outlet.

3. In a gasolene-burner, the combination with a main jet-piece and apipe for supplying a jet of vapor to the main jet-piece; of an auxiliaryjet-piece connected with said pipe and arranged to direct a jet ofgasolene or vapor along beneath the pipe; a shell arranged beneath thepipe to inclose the et and provided at intervals with inlets to admitair, and with an outlet at the end opposite the auxiliary jet-piece andan imperforate mixer-section between the air-inlets and the outlet.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, at Los Angeles, California, this28th day of December, 1890.
